Introduction
ISO 10140 (all parts) concerns laboratory measurement of the sound insulation of building elements
(see Table 1).
This part of ISO 10140 specifies the application rules for specific elements and products, including
specific requirements for preparation, mounting, operating and test conditions. ISO 10140-2 and
ISO 10140-3 contain the general procedures for airborne and impact sound insulation measurements,
respectively, and refer to ISO 10140-4 and ISO 10140-5 where appropriate. For elements and products
without a specific application rule described in this part of ISO 10140, it is possible to apply ISO 10140-2
and ISO 10140-3. ISO 10140-4 contains basic measurement techniques and processes. ISO 10140-5
contains the requirements for test facilities and equipment. For the structure of ISO 10140 (all parts),
see Table 1.
ISO 10140 (all parts) was created to improve the layout for laboratory measurements, ensure
consistency and simplify future changes and additions regarding mounting conditions of test elements
in laboratory and field measurements. It is intended for ISO 10140 (all parts) to present a well-written
and arranged format for laboratory measurements.
It is intended to update this part of ISO 10140 with application rules for other products. It is also
intended to incorporate ISO 140-18 into ISO 10140 (all parts).

ISO 10140-1:2016(E)
Annex A
(normative)
Walls — Airborne sound insulation
A.1 General
For walls and other partitions, ISO 10140-2 is applicable. This annex is applicable to lightweight twin
leaf partitions, such as those constructed of gypsum boards.
The quantity determined is the sound reduction index, R, as a function of frequency. The definition of R
is given in ISO 10140-2.
The general guidelines in the relevant clauses of the basic ISO 10140-2 shall always be followed.
A.2 Test element
The test opening for walls should be approximately 10 m .
A.3 Boundary and mounting conditions
The sound reduction index of lightweight twin leaf partitions (e.g. twin leaf gypsum board walls) is
influenced by the mounting conditions in the test opening of the laboratory. Important installation
parameters include the niche depth and the position of the partition in relation to the acoustic break in
the test aperture.
Key
1 source room
2 receiving room
3 acoustic break of the laboratory
Figure A.1 — Example of the position of the test element relative to the acoustic break of the
laboratory
To improve the reproducibility between laboratories and facilitate comparison of sound reduction
indices for different lightweight double walls, the twin leaf partition shall not be mounted across the
ISO 10140-1:2016(E)
acoustic break of the laboratory, but on the same side of the break, as indicated in Figure A.1. The
aperture should meet the requirements in ISO 10140-2.
Other mounting conditions may be used but shall be fully described in the test report.
NOTE 1 Mounting the lightweight partition with one leaf on one side and the other leaf on the other side of the
acoustic break can result in higher values for the sound reduction index.
NOTE 2 Other mounting conditions can be suitable for certain types of twin leaf walls, for example walls for
semi-detached houses where the leaves are vibrationally uncoupled (for example on separate foundations). In
such cases, the wall leaves can be mounted on each side of the acoustic break.
A.4 Test and operating conditions
The test and operating conditions are given in ISO 10140-2.
A.5 Test report
The test report is given in ISO 10140-2.

ISO 10140-1:2016(E)
Annex B
(normative)
Doors — Airborne sound insulation
B.1 General
This annex is applicable to internal and external doors (including door sets).
The quantity determined is the sound reduction index, R, as a function of frequency. The definition of R
is given in ISO 10140-2.
The general guidelines in the relevant clauses of the basic ISO 10140-2 shall always be followed.
NOTE For a definition of door, see ISO 1804 and EN 12519.
B.2 Test element
For most doors, a test opening with an area of less than 10 m is needed. The area of the test element, S,
is the area of the opening in the filler wall required to accommodate the door.
B.3 Boundary and mounting conditions
The test opening for doors shall be arranged such that the lower edge is situated near to the level of
the floor of the test rooms and such that conditions in the building are reproduced. The door shall be
installed for test such that it can be opened and closed in a normal manner.
B.4 Test and operating conditions
The door shall be opened and closed at least five times immediately before testing.
B.5 Test report
The test report is given in ISO 10140-2.
ISO 10140-1:2016(E)
Annex C
(normative)
Windows — Airborne sound insulation
C.1 General
This annex is applicable to windows.
The quantity determined is the sound reduction index, R, as a function of frequency. The definition of R
is given in ISO 10140-2.
The general guidelines in the relevant clauses of ISO 10140-2 shall always be followed.
NOTE For a definition of window (terminology), see EN 12519.
C.2 Test element
The preferred dimensions of the test opening for a window are 1 250 mm × 1 500 mm as for the specific
small-sized test opening described in ISO 10140-5, but variations from this size can be necessary in
recognition of national building practice. For windows, the test opening may be staggered as shown
in ISO 10140-5:2010, Figure 3. In the case of a window assembly, dimensions may be chosen as
representative of the assembly used in practical circumstances. For windows, the area, S, is the area of
the opening in the filler wall required to accommodate the test element.
C.3 Boundary and mounting conditions
The installation of a window assembly shall be as similar as possible to the method which would be used
in practice. When the window is mounted in the test opening, the niches on both sides of the windows
shall have different depths, preferably in a ratio of about 2:1, unless this conflicts with the particular
design of the window. However, it is expected that results obtained with niche depths of different ratios
would differ.
The gap between the window and the test opening (about 10 mm to 13 mm around the window when
mounted in the test opening) should be filled with absorbing material (for example mineral wool)
and made airtight using an elastic sealant on both sides or in accordance with the manufacturer’s
instructions.
If the test element is intended to be readily openable, it shall be installed for the test in such that a way
it can be opened and closed in a normal manner.
C.4 Test and operating conditions
C.4.1 Conditioning
The sound insulation of certain glazing systems or elements, especially those incorporating laminated
glass, can depend on the room temperature during the measurements. The temperature of both rooms
used for measuring the sound insulation should be (20 ± 3) °C. The test elements should be stored for
24 h at the test temperature. In addition, it can be advantageous to make measurements at temperatures
similar to those for which the test element is designed.
6 © ISO 2016 – All rights reserved

ISO 10140-1:2016(E)
C.4.2 Operation
If the test element is intended to be openable, it shall be opened and closed at least five times immediately
before testing.
C.5 Test report
The test report is given in ISO 10140-2.
ISO 10140-1:2016(E)
Annex D
(normative)
Glazing — Airborne sound insulation
D.1 General
This annex is applicable to glazing.
The quantity determined is the sound reduction index, R, as a function of frequency. The definition of R
is given in ISO 10140-2.
The general guidelines in the relevant clauses of ISO 10140-2 shall always be followed.
NOTE For a definition of glass (terminology), see EN 12758.
D.2 Test element
The dimensions of the test opening for glazing shall be 1 250 mm × 1 500 mm with an allowable
tolerance on each dimension of ±50 mm, preferably maintaining the same aspect ratio. For glazing,
the test opening shall be staggered on both sides and on the top by a distance of between 60 mm and
65 mm. The glazing shall be mounted in the smaller opening as shown in Figure D.1. For glazing, the
area, S, is the area of the opening in the filler wall required to accommodate the test element.
The specific small-sized test opening described in ISO 10140-5:2010, Figure 3, fulfils these criteria, and
a test opening in accordance with ISO 10140-5:2010, 3.3.2, shall be used.
NOTE Details of the measurement conditions for glazing are prescribed in order to ensure the best possible
comparison between results obtained by different laboratories.
D.3 Boundary and mounting conditions
The glazing shall be installed into the test opening such that the niches on both sides of the pane have
different depths with a ratio of 2:1. A gap of about 10 mm shall remain between the pane and the reveal
of the test opening. This gap shall be filled with a type of putty, which shall be tested as described
below. To fix the glazing, two wooden beads (25 mm × 25 mm) shall be used (see Figure D.1). The space
between the glazing and the wooden beads shall be filled with putty about 5 mm thick. The beads shall
1)
cover not more than 15 mm and not less than 12 mm of the glass .
The putty used for filling the 10 mm gap between the perimeter of the glazing and the reveal of the
test opening, and the 5 mm gap between the glazing and the wooden beads shall be qualified by the
following test method. A single soda-lime/silica glass pane (float, density 2 500 kg/m , modulus of
elasticity E = 7 × 10 MPa) with a thickness of (10 ± 0,3) mm and dimensions of 1 230 mm × 1 480 mm
shall be mounted with this putty in accordance with Figure D.1. The airborne sound reduction index
shall be determined in one-third octave bands in the frequency range from 1 600 Hz to 3 150 Hz. The
first measurement shall begin not later than 1 h after mounting. The results shall be as follows, to
within ±2,0 dB:
— 1 600 Hz: R = 31,3 dB;
— 2 000 Hz: R = 35,6 dB;
1) This method of mounting and sealing a glass pane into the test opening is given as a practical, quick and
reproducible solution, although this is not the type of mounting in practice.

ISO 10140-1:2016(E)
— 2 500 Hz: R = 39,2 dB;
— 3 150 Hz: R = 42,9 dB.
A second measurement shall be taken about 24 h later in order to make sure that no hardening process
is influencing the measurement. No systematic deviation average, ΔR (mean of the four ΔR values),
greater than 0,5 dB is permitted.
2)
NOTE Perennator TX 2001 S has been shown to fulfil these conditions.
The sound insulation measured for a type of glazing does not necessarily represent the sound insulation
of a window with that glazing. Preferably, therefore, the complete window should be measured as well
to obtain information on the sound insulation of the window and not only the glazing.

ISO 717-1. For laminated glasses, owing to temperature dependency, it is recommended that the
specimen temperature should be (20 ± 3) °C.
For best reproducibility, it is recommended that the test opening for glass panes, as described in this
part of ISO 10140, be adopted.
Some variation in panel size, etc., to those in ISO 10140 (all parts), may be necessary for the testing
of glazed assemblies, i.e. glass blocks, paver units, channel-shaped glass, structural sealant glazing
and structural assemblies, in order to include a valid representation of all their features. Acoustic
measurements of the performance of these products shall be made on assemblies or arrays of them and
not of individual elements. Factors which influence testing are size, jointing, etc.
Test reports on the sound insulation of glazing shall be obtained from measurements made under the
conditions specified in ISO 10140 (all parts) or, as closely as possible, for some unconventional glass
products or assemblies, as acknowledged above. In all cases, constructional details shall be included,
with statements, where appropriate, of:
a) type of glass;
b) glass thickness(es);
c) airspace(s)/cavity width(s);
d) gas filling - type and concentration;
e) edge seal profile, edge seal materials and edge seal components;
f) for laminated glass, glass/plastics sheet material/interlayer build up - type, thickness(es) and number;
g) for laminated glass, the specimen temperature;
h) description of the particular mounting conditions for assemblies of glass blocks, pavers units,
channel-shaped glass, structural sealant glazing and structural assemblies due to the necessary
deviation from the prescribed conditions of ISO 10140 (all parts).
D.4.2 Reference curves
D.4.2.1 General
These shall be determined by measuring two reference insulating glass units (IGU) as defined in D.4.2.2
and D.4.2.3. Reference curves shall be determined when the test equipment is set up and then checked
at least once a year or before each new glazing measurement.
In case of doubt concerning the results obtained using the reference IGUs, then a specimen of single
glass, i.e. 10 mm float glass in accordance with EN 572-1 and EN 572-2, shall be measured to check
repeatability.
D.4.2.2 Reference IGU 6(16)6
The sound reduction index (SRI) of a reference 6(16)6 IGU, as described in Figure D.2, shall be in the
range as given in Table D.1.

Annex E
(normative)
Small technical elements — Airborne sound insulation
E.1 General
This annex is applicable to small technical elements, for instance air intakes and other elements smaller
than 1 m , such as profiles and shutter boxes.
The acoustic performance of the element is expressed in the element-normalized level difference, D
n,e
per unit, as defined in ISO 10140-2.
The general guidelines in the relevant clauses of the basic ISO 10140-2 shall always be followed.
For small technical elements, the sound reduction index is less suitable as a descriptor because the area
of the test element is not normally well defined and the performance is not necessarily proportional to
the area of the test element. Therefore, the performance is expressed as a normalized level difference
for a specific unit. Furthermore, due to the small dimensions and mounting conditions, the direct
environment around the test element and nearby objects can have a large influence on the results and
should therefore be carefully specified.
E.2 Test element
E.2.1 General
Ensure that the test element is installed in a manner representative of field practice using normal
connections and sealing conditions at the perimeter and at joints within the unit.
The building elements are small and, in combination with the spatial variations of the sound fields, this
leads to significant dependency on their position; it is therefore recommended more than one position
of the test element be used (see E.2.2).
In order to achieve a realistic wall thickness around the element, it may be practical or necessary to
either increase or decrease the thickness of the partition wall in the area around the element (see E.2.3
and E.2.4).
When a small building unit is mounted near one or more reflecting planes, the sound transmission can
differ appreciably from that obtained when the unit is mounted through a partition, but away from
any adjoining room surface. Therefore, mount the equipment selected for testing through the partition
in positions representative of normal usage. If natural corners or edges are not available in the test
opening, it is essential to simulate such mounting conditions by attaching reflective panels at right
angles to the partition wall, as described in E.2.5.
E.2.2 Number of positions
Three positions should be used for the mounting of the test element in the partition wall. These positions
shall either be simulated, as described in E.2.5, or they shall be located at least 1,2 m from each other.
A dependency on position also occurs for apparently equivalent corners; this makes it necessary to use
more than one corner.
NOTE When simulating corner or edge positions by attaching reflective panels, it is possible to achieve the
necessary position averaging by changing the locations and orientations of the reflective panels while the test
element stays in the same position.
ISO 10140-1:2016(E)
E.2.3 Local increase of wall thickness
Instead of changing the thickness of the complete partition wall, simulate various wall thicknesses
by adding extra panels with a mass per unit area of more than 10 kg/m to the original partition
construction. The edges of such additional panels shall be at least 0,5 m from any part of the test
element.
E.2.4 Local decrease of wall thickness
If a thick partition wall is needed to achieve a sufficiently high flanking transmission loss, create a
realistic wall thickness around the test device by locally reducing the thickness using panels. This shall
be done in accordance with Figure E.1.
Key

The panels shall be sealed with tape along the edges.

The following relations shall hold:
a) l > 0,6 m;
b) l > 0,1 m; if l > 0,5 m in every direction, no smooth transition of thickness is necessary;

c) α < 30°.
E.2.5 Central, corner and edge positions
E.2.5.1 Equipment used away from walls
Install equipment mounted through a partition but normally located away from an adjoining wall, floor
or ceiling in such a manner that no part is within 1,00 m of a surface at right angles to the mounting
surface; 0,85 m is sufficient, if several elements are tested
